Bearing stark resemblance to his ancestor Kagami Uchiha, Shisui has short, unkempt, black hair, dark eyes, a relatively broad nose and defined eyelashes. He's 18, of tall yet lean stature, and wears the standard attire of the Uchiha clan which includes a high-collared, dark-coloured outfit along with a tantō strapped to the right side of the back of his shoulder, fastened with a chest harness.
